Milwaukee 48-20-9022 Carbide Hammer Drill Bit 3/8x12 in

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-20-9022 is a carbide-tipped hammer drill bit engineered for demanding masonry and concrete drilling applications. Measuring 3/8 inches in diameter and 12 inches in overall length, this bit features a reinforced carbide tip designed to extend service life under repeated impact stress. It is compatible with both impact drivers and standard hammer drills, making it a versatile addition to any trade toolkit. The SHOCKWAVE Impact Duty construction is built to handle the torsional loads generated by high-torque impact tools without premature tip failure or shank damage. Licensed tradespeople and skilled installers working in commercial and residential settings will find this bit suited to high-cycle drilling tasks.

This bit is used wherever 3/8-inch holes are required through masonry, concrete block, or similar hard substrates. Typical applications include anchoring work for mechanical, electrical, and plumbing trades, as well as structural fastening in both new construction and retrofit installations. The 12-inch working length provides the reach needed for through-wall penetrations and deep anchor-bolt applications that shorter bits cannot access. It is sold in a package quantity of 3 units, making it practical for multi-hole projects or crew supply.
